An extract from Waypoints, the new book by Scottish writer, artist and storyteller Ian Stephen, in which adventure, memoir and storytelling combine to form a beautifully written account of sea journeys from Scotland's west coast.

The islands of the Outer Hebrides are home to many mysterious structures – stone circles, beehive dwellings, holy wells and ’temples’ from the Celtic era. In a remarkable new book, Alastair McIntosh returns to the islands of his childhood and explores not only the meaning of these places, but wider moral concerns around the idea of a just war, globalisation and ecology.
